Question

Receiving this error on Android 4.4 device when starting my app. App immediately crashes. However I don\'t have this error on Android 5.1 device. Any clue?

Answer 1

For those who have already activated MultiDex and still get this exception, it's just a stupid Android Studio / Gradle issue.

Try cleaning project, toggling Instant Run in settings, and rebuilding the project.
